I also pay attention to whether the seat meets current safety standards and whether it has features like a secure harness system and anti-rebound protection. For me, these details help reduce stress every time I put my child in the car.

Comfort for My Baby
I always consider whether my baby will be comfortable during short errands and longer drives. I look for soft padding, adjustable inserts for newborns, and a canopy that gives good coverage. A seat with enough head support and a snug fit helps me feel my baby is secure and cozy at the same time.
